Taiwan is pushing a sharper case at this year's UN General Assembly, framing China's pressure campaign as a threat to global security — bad news for Beijing's diplomatic messaging, and a sign tensions around the strait are hardening.

• Taiwan's foreign ministry laid out three demands ahead of the assembly opening in New York on September 8.
• The core argument stays the same: the 1971 UN resolution that gave China its seat never said Taiwan cannot take part, and Beijing has twisted it to erase Taiwan's status.
• New this year is a direct focus on peace in the Taiwan Strait — any attempt to change the status quo by force breaks the UN charter itself.
• Taiwan points to China's military intimidation, cyberattacks, and economic pressure, plus a new Chinese law passed in July that lets Beijing reach across borders to police people abroad.
• Taiwan's diplomatic allies will again send a joint letter to the UN secretary-general and speak up during the general debate later in September.

Outlook: Taiwan will not get in, but expect its allies and Western governments to keep raising China's long-arm enforcement law as the debate runs through late September.
